The Galapagos Islands are an archipelago of geologically young volcanic islands. In fact the islands of Isabela and Fernandina are still being formed. The last volcanic eruption was in 2009.
The archipelago is located on the equator 525 miles west of Ecuador, of which it is a territory (Population 30,000). There are 15 main islands (the largest is Isabela), 3 smaller islands, 107 rocks and islets. The distance from the northernmost to the southernmost islands is 137 miles. The total land area is 3,040 sq. miles, scattered over 17,000 sq. miles of the Pacific Ocean. Darwin arrived here in September, 1835 aboard The Beagle and the rest, as they say, is history (or Evolution)!
